In order, therefore, to obtain the best results, permanent indentification should be placed upon the various racks 4 so that proper use can be made of them.

Since there are no racks 4, ordinarily, in the bottom of the compartments, it is necessary to attach the plates 1 to these by a different method and a modification, such as shown in Figure & is provided which can be attached to the bottom of the compartments at a, as shown in Figure 1 by screws or nails.

With reference now to Figures 3 and 4:, it is pointed out that the wording upon the plates 1 is calculated not only to indicate the temperature 'at that location and the kinds offood tobe. placed upon the rack 4-. to which the plate 1 is attached but indicates at b the name of the firm from whom ice may be purchased and therefore provides a desirable means of advertising for the dealer which is constantly before the customer whenever the refrigerator is opened.

Manifestly, the construction shown is capable of considerable modification and such modification as is considered within the scope and meaning of the append-ed claims is also considered within the spirit and intent of the invention.

Whatis claimed is: I

1. The herein described method which consists initially in predetermining the varying degrees of temperature at diflerent points in said ice box and in aflixing a label at each of said points designating the temperature and specifying the commodities best suited for the designated temperature.

2. The herein described method which consists initially in obtaining a check of the degrees of temperature at different points in said ice boXes and in designating the normal temperature by visible means and in specifying the character of foodstuffs best preserved in the temperature designated.

. In testimony whereof we aflix our signatures.
